I have had a nasty toothache for about a week, and it has severely affected my sleep quality. It has been impossible to sleep for more than 2-3 hours at a time. Not only have I been sleeping lighter, but my dreams have been bad. I have had to watch or listen to bad things happen to various creatures. Those dreams have been so disturbing that it has been hard to fall asleep again after them.
This weekend, the infected part finally burst open and the toothache calmed down. I slept peacefully the night before Saturday with no bad dreams.
After a WBTB this morning, I got a nasty dream about bleeding, pain, and disgusting things happening to my body. I woke up to find out that my period was starting.
The physical pain must have influenced my dreams. I wonder how common this is.
